-fdelete-null-pointer-checks flag controls global dataflow analyses and eliminate useless checks for null pointers; It assume that if a pointer is checked after it has already been dereferenced, it cannot be null. This flag is enabled by default.
gcc v4.9 has more optimizations added to this option. Hence it is very aggressive with GCC v4.9 series. Add -fno-delete-null-pointer-checks to disable the optimization
